Abstract

The brake is arranged in such way, that at an activation of an operating element of the motor vehicle, characteristic for an end of its operation, a parking brake of the motor vehicle is automatically activated. The parking brake is automatically released at an activation of an operating element, which signifies a renewed operation of the motor vehicle. The parking brake is preferably released hydraulically, and is operated with spring power, whereby a dedicated hydraulics circulation is provided with pump (6), spring (7), control valve, brake cylinder, and ventilation valve (8). The control valve is preferably a magnetic valve (2) with time delay.

Description

Die Erfindung bezieht sich auf eine automatisierte Feststellbremse für Kraftfahrzeuge.The invention relates to an automated Parking brake for motor vehicles.

Bei manuell zu betätigenden Feststellbremsen von Kraftfahrzeugen besteht die Gefahr, daß die Fahrer beim Verlassen des Fahrzeugs vergessen, dieses gegen unbeabsich­ tigtes Wegrollen zu sichern. Dies kann zu erheblichen Per­ sonen- und Sachschäden führen.With manually operated parking brakes from Motor vehicles run the risk that the driver when Forget leaving the vehicle, this against unintentional secure rolling away. This can lead to significant per cause damage to persons and property.

Der Erfindung liegt die Aufgabe zugrunde, die Betäti­ gung der Feststellbremse zu automatisieren.The invention has for its object the Betäti automation of the parking brake.

Diese Aufgabe wird mit einer, auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen automatisierten Feststellbremse gelöst.This task comes with a, including the distinctive Features of the generic claim having the main claim automated parking brake released.

Ein Signal, das durch eine das Ende des Fahrbetriebs charakterisierende Betätigung eines Bedienelements des Kraftfahrzeugs gesetzt wird, steuert die Betätigung der Feststellbremse des Kraftfahrzeugs. Ein weiteres Signal, das durch eine die Aufnahme des Fahrbetriebs charakterisie­ rende Betätigung eines Bedienelements des Kraftfahrzeugs gesetzt wird, steuert wiederum das Lösen der festgebremsten Feststellbremse des Kraftfahrzeugs.A signal that indicates the end of driving characteristic operation of a control element of the Motor vehicle is set, controls the actuation of Parking brake of the motor vehicle. Another signal this is characterized by the start of driving rende actuation of a control element of the motor vehicle is set, in turn controls the release of the braked Parking brake of the motor vehicle.

Vorzugsweise wird die Feststellbremse hydraulisch ge­ löst und mit Federkraft betätigt.Preferably, the parking brake is hydraulically ge releases and operated with spring force.

In einer vorteilhaften Ausgestaltung der Erfindung gibt ein eigener Hydraulikkreis mit Pumpe, Federspeicher, Steuerventil, Bremskolben und Entlüftungsventil die Fest­ stellbremse frei.In an advantageous embodiment of the invention has its own hydraulic circuit with pump, spring-loaded,  Control valve, brake piston and bleed valve the fixed Parking brake released.

Dabei ist das Steuerventil vorzugsweise ein Magnetven­ til mit Zeitverzögerung.The control valve is preferably a magnetic valve til with time delay.

Vorzugsweise wird das Signal zum Festbremsen bzw. Lö­ sen der Feststellbremse durch die Betätigung des Licht­ schalter an der Fahrertür beim Schließen und/oder des Tür­ schlosses an der Fahrertür und/oder einer elektrischen Weg­ fahrsperre und/oder des Lenkschlosses und/oder des Zünd­ schlosses gesetzt.The signal for braking or releasing is preferably used the parking brake by operating the light switch on the driver's door when closing and / or the door lock on the driver's door and / or an electrical path lock and / or the steering lock and / or the ignition lock set.

Eine unbeabsichtigte Betätigung der Feststellbremse bei voller Fahrt, beispielweise auf der Überholspur auf einer dichtbefahrenen Autobahn könnte zu einer verheerenden Auffahrunfallserie führen. Deshalb ist ein Sicherungskon­ zept für den Fall von Fehlsignalen, beispielsweise durch Fehlkontakte, Kurzschlüsse oder Kontaktunterbrechungen un­ erläßlich. In einer solchen Sicherheitsbetrachtung kann ein zusätzliches Signal in die Steuerung der Feststellbremse aufgenommen werden, das bei einer gewissen Mindest- Geschwindigkeit des Kraftfahrzeugs das Festbremsen der Feststellbremse verhindert.Unintentional activation of the parking brake at full speed, for example in the fast lane A busy highway could be devastating Run rear-end collision series. Therefore, a security account accept the case of false signals, for example by Faulty contacts, short circuits or interruptions in contact negligible. In such a safety assessment, one can additional signal in the control of the parking brake be recorded, which at a certain minimum Speed of the motor vehicle braking the Parking brake prevented.

Ein solches Geschwindigkeits-Vetosignal macht vorzugs­ weise bei einem bewegten Fahrzeug das Signal zum Festbrem­ sen der Feststellbremse unwirksam.Such a speed veto signal is preferred when the vehicle is moving, the signal to brake parking brake ineffective.

Eine unbeabsichtigte Betätigung der Feststellbremse kann auch bei einem Hydraulikdruckverlust auftreten, da in diesem Fall der Gegendruck zu der Feder zur Betätigung der Feststellbremse wegfällt und die Feststellbremse greift. Unintentional activation of the parking brake can also occur if there is a loss of hydraulic pressure, as in in this case, the back pressure to the spring to actuate the Parking brake is removed and the parking brake engages.  

Das Eingreifen der Feststellbremse bei Hydraulikdruckver­ lust kann vorzugsweise durch eine Fang-Nase unterbunden werden, die bei gegebenem Geschwindigkeits-Vetosignal das Aus rücken der Feder zum Festbremsen der Feststellbremse verhindert.The engagement of the parking brake with hydraulic pressure ver lust can preferably be prevented by a catch nose which, for a given speed veto signal From the back of the spring to brake the parking brake prevented.

In einer anderen vorteilhaften Ausgestaltung der Er­ findung wird bei Hydraulikdruckverlust bei gegebenen Ge­ schwindigkeits-Vetosignal die Widerlagerung der Feder zum Festbremsen der Feststellbremse freigegeben. Damit fällt die Gegenkraft der Feder weg und die Feder wird kraftlos.In another advantageous embodiment of the Er In the event of loss of hydraulic pressure at given ge speed veto signal the abutment of the spring to Parking brake released. With that falls the counterforce of the spring is gone and the spring becomes weak.

Vorzugsweise wird das Geschwindigkeits-Vetosignal bei bewegtem Fahrzeug an der Getriebeabtriebswelle abgenommen.Preferably, the speed veto signal is at removed moving vehicle on the transmission output shaft.

In einer Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Diese Figur zeigt ein Blockschalt­ bild einer automatisierten Feststellbremse.In a drawing is an embodiment of the Invention shown. This figure shows a block circuit image of an automated parking brake.

Ein oder mehrere Kontaktgeber 1 geben ein Signal zur Steuerung eines Magnetventils 2 mit Zeitverzögerung. Dieses Magnetventil 2 steuert den Druck in einem Hydraulikzylinder 3, dessen Kolben 4 der Federkraft der Federn 5 zur Betäti­ gung der Feststellbremse entgegenwirkt. Bei Signal "frei" wird ein hoher Druck eingestellt und der Kolben 4 des Hy­ draulikzylinders 3 öffnet die Feststellbremse. Bei Signal "festgebremst" wird ein niedriger Druck eingestellt und der Kolben 4 des Hydraulikzylinders 3 gibt den Federn 5 nach und die Feststellbremse wird geschlossen. Der Druck im Hydraulikkreis wird durch eine Pumpe 6 erzeugt und durch einen Federspeicher 7 gepuffert. Ein Entlüftungsventil 8 entlüftet den Hydraulikzylinder 3.One or more contactors 1 give a signal to control a solenoid valve 2 with a time delay. This solenoid valve 2 controls the pressure in a hydraulic cylinder 3 , the piston 4 of which counteracts the spring force of the springs 5 for actuation of the parking brake. With signal "free" a high pressure is set and the piston 4 of the hydraulic cylinder 3 opens the parking brake. With the signal "braked", a low pressure is set and the piston 4 of the hydraulic cylinder 3 yields to the springs 5 and the parking brake is closed. The pressure in the hydraulic circuit is generated by a pump 6 and buffered by a spring accumulator 7 . A vent valve 8 vents the hydraulic cylinder 3 .
